Have a '06 Monte LT with 110,000 miles. Theres chassis creaking sounds in the front it sounds like. Heard the struts weren't worn out. Got new front engine mount too.
Thanks, Gary

 

It could be the bushings in your suspension parts causing the creaking sound. They do dry out over time and cause noises. You can buy new parts on ZZPerformance | 3800 Performance Parts | Largest Aftermarket Supplier! fairly cheaply that are true upgrades over what your car came with stock, or it may be as simple as replacing the lower control arm, just depends on where the noise is actually coming from and this can be kind of hard to diagnose on a good day, if you can have a friend listen while you push down on the front of the car it may help you locate the actual culprit.

 

I have replaced all 4 struts, replaced the rear sway bar links with Mevotech poly ones and now I am getting a little annoying creak while driving,it doesn't do it when manually pushing down on suspension or hard cornering,just a creaking noise!! coming from the pass rear??

 

I do recall I had the steering bushings replaced a year ago. My brother has a '07 of same similar noises. He had struts done, same noises. Going to dealership for the defective unintended recall 14299 ignition key rotation, and will ask them for the official GM tech what the problem is. But might cost me!!
